Our Premium Waterproofing System
This suggested means of application should be followed in any situation
where optimum waterproofing and water pressure resistance is
necessary. For a Superior five-Coat System: three coats or three gallons
per 100 sq. ft. of Vapor-Barrier embedded into polyester reinforcement
fabric and top-coated with two coats or two gallons per 100 sq. ft. of
Ames’ Block & Wall. The reinforcement fabric ensures that the coating
cannot crack or fracture and stops walls from the danger of cracking and
substantially increases wall strength up to 100 psi. The best suggested
sequence of application is as follows:
1. Clean the surface thoroughly. (See surface preparation instructions.)
2. Fill all cracks. (See surface preparation instructions.) Make sure your
surface is as smooth as possible. The final appearance of your wall will
depend on the thoroughness of your preparation work. Prepare the wall
to be waterproof (imagine yourself building a water tank).
3. Seam tape all joints and cracks until the wall is sealed. For best
results use Ames Peel & Stick Adhesive Seam Tape (PS250, PS450,
PS650). The surface must be reasonably smooth for fabric application
and must contain no air pockets.
4. Wet the wall liberally with Vapor-Barrier or Ames’ Block & Wall coating
and roll the fabric into the wet wall and topcoat the fabric. The goal here
is to spread the coating out into a path as wide as the reinforcement
fabric you are using. Take care that the fabric lays flat to the wall without
air bubbles or pockets. The use of fabric is important because it
substantially increases the strength of the coating and should
dramatically increase the life of the wall surface. Allow to dry completely.
On smooth surfaces one gallon should cover 100 sq. ft. per coat.
5. Apply two coats of Vapor-Barrier over the embedded fabric at a rate of
one gallon per 100 sq ft. per coat. Ensure that any pinholes are sealed.
Allow adequate drying time between coats. At this point your wall should
be totally waterproof. Wash the surface completely after the final coat of
Vapor-Barrier has dried. This will remove any curing residue and will
improve adhesion.
6. Topcoat the Vapor-Barrier with two coats of Block & Wall. If below
grade Vapor-Barrier may be substituted. Apply this product with a paint
roller, brush or sprayer at a rate of one gallon per 100 sq. ft. per coat.
Again, allow adequate drying time between coats. When finished, there
should be a total of five coats on your wall, or five gallons per 100 sq. ft.
with the reinforcement fabric and Seam Tape embedded.
